This invention rename devices for use in'connection with-heating systems for gen erating steam to increase the water vapour 'contentof the air of an apartment and for Busing-surplus steam generated to improve system, and my objectis'to devise simple and easily controllable. means forthis purpose which may be easily installed in connection 10 with "ordinary heating apparatus.

I attain my objectbymeans of constructions which maybe briefly described as follows. A vaporizer is located in the combustion chamber of the furnace of the heating system. Water is fed in a steady flow to the vaporizer and the generated steam is led to a'suitable place of discharge. Thepipe through whichthe steam is led off is provided 1 e with a controlling Valve and a steam jet is v 9 provided on the vaporizer through which surplus steam is discharged into the combustion chamber of the furnace to aid combustion, or elsewhere if desired. The water supply means is preferably formed as a unitary cast- 725 ing including a drip, a trap into which the drip dischargesand with which the vaporizer is connected, and an overflow discharging to a waste pipe.

The device is hereinafter more specifically 30 described and is illustrated in the accompanying drawings in which Fig. 1 is a front elevation'of a furnace hav- 7 in my device installed therewith;

' Inthe drawings, 1 is a furnace which may be of any ordinary construction and is proid d with the fuel door 2 leading into the combustion chamber over the fire pot. In the combustion chamber is located a vaporizer 3, preferably of the tubular form shown. With this vaporizer are connected the water Supply pipe 4 and steam pipe 5, preferably 3 a side' elevation of the vaporizer supply pipe 4 and the vaporizer is, however, I

located above the axis ofthe vaporizer so by means of the special connection shown in Fig 3, which is formed-as a unitary casting having a connection 6 for the attachment of the vaporizer and two branches 7 and '8, one in approximate alinement withthe vaporizer combustion in the furnace of the heating angled pipe connections 9 and 10Jconnected respectively with the water supply pipe 4 and steam pipe 5, which'extend through the side of the frame of the fuel door opening. I, I

lnthe modification shown in Fig. 4, the w'aterpipe is connected with the forward end of the vaporizer by the connections 11, while the steam pipe 5 is connected by means of suitablepiping 12 with the inner end of the vaporizer. The construction of Fig. 3 is,'however, preferred. 1

-The water pipe 4 is supplied with water by water supply means 13, preferably formed asa unitary casting. This casting is shaped to form an open chamber 14, a connection 15 for the water pipe 4, a trap 16 between the two,.a waste pipe 17, and an overflow 18 preferably extending from the side ofthe chamber 14 over the upper end of the waste pipe 17. The waste pipe 17 is connected with a position for discharge. V

The various parts described are soproportioned and positioned that when water is dripping from the overflow 18 the water level is-partway'v only up above the lower side ofthe water pipe 4, leaving a steam sp'ace'in the pipe and also in the upper part of the vaporizer. The connection between the water pipe 19'which may be led to any convenient that there w'illiusual'ly be a .greater depth of water in the vaporizer than in the water pipe. When water is supplied to, the chamber 14 to maintain vthis water level, which is of course governed'by the position of the overflow, steam will be generated in the vaporizer chamber and discharged through the steam pipe 5. This steam pipe is connected by'a coupling 20 with the pipe 21 which-is led to a discharge outlet 22 located in the floor of. an apartment above the furnace or to any other position desired. In this pipe is located 7 a valve 23 whereby the amount of steam discharged from the outlet 22 may be controlled.

To ensure that an adequate supply of steam will be delivered at all times even when a low fire only is maintained in the furnace, I prefer to give. the vaporizer sufficient heating surface to. generate-steam in excessof the requirements when a strong fire is maintained. This excess steam must be given some means of'escapeiand. I therefore provide inacorn venient position an outlet for this, excess steam, which excesssteam is preferably led into the interior of the'furnace'to assist smoke prevention. Preferably I provide a small outlet 24 in the casting 6', preferably valve controlled, whereby the outlet may be moreor less. restricted as may be necessary to compensate for the resistance'tothe How of steam to the outlet 22 which depends to a considerable extent on the distance of the outlet from the furnace. By controlling the outlet 2}, an. adequate supply is assuredto the outlet 22', whileby using the valve 23 the amount of steam passing from the outlet 22 may be regulated, any excess passing away through theoutlet 2e. Preferably the water supply pipe i and the steam pipe 5 are connected by'the pipe 25-so that any steam passing backthrough the water pipe may pass up to the steam pipe 5 and thence to the pipe 21, and any drip back through thepipe 21 isledj directly to the water supply pipe.

The watersupply means'is fed by the water pipe 26, which will usually be connected with a water supply service. Formed integral :ith the wallof the chamber 14 is a connection 27 for the pipe 26. Thisconnection has a side outlet with which is connected the drip valve 28 which discharges into the chamber 1%. By means of this valve a suitable quannty of water is regularly supplied to the chamber so that when the device is in opera tion a drip is'maintained from the overflow 18', thus ensurmg the maintenance of a constant water level in the system. The bottom of the drip 16 is preferably provided with a sediment chamber closed by the plug 29.

In the form of vaporizing chamber shown in Fig. l, the valve controlled outlet 24: is

shown at the connection between the steam pipe 5 andthe piping 12.
